ENVELOP.

Specification of Letters Patent.

Patented May 9, 1916.

Application filed January 27, 1914. Serial No. 814,662.

To all w hum it may concern Be it known that I, GEORGE I RANCIS Ho- GAN, a citizen of the United States, residing at Chicago, county of (look, State of lllinois, have invented certain new and useful Improvements in Envelops; and I do hereby declare the following to be a full, clear, and exact descri 'ition of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

in mailing merchandise in unsealed envelops of ordinary type having a flap so cured ,with a metal fastener, there is always danger that the merchandise will crowd against the flap and finally distort or tear it and spill the merchandise. There is also danger of tearing the envelop when the merchandise is being inserted, particularly if themerchandise consists of circulars, catalogues, or the like, of paper.

l t is an object of. the present invention to provide an envelop so constructed that the closure end will be stronger than when a single flap is used, thus obviating some of the danger of distorting the flap and losing the contents; and it is a further object of the invention to so shape the closure end of the envelop that the merchandise can be easily inserted and without danger of tearing the envelop during this filling operation. I

To this end the envelop of the present invention is provided with a pair of flaps. one attached to the front of the envelop and the other to the back thereof, and both adapted to fold down against the back wall for attachment to a metal fastener there secured.

The particular advantages of the present ,invention will be made clear by the follow ing (,letailod description, which is 10 be taken in conjunction with the accompanying drawings, whereiir Figure l is an elevation showing the rear oi" the envelop with the flaps folded down to close the filling end; Fig. 2 is a perspeo tive View of the envelop partly opened up; Fig. 3 is an elevation showing the llaps before they are folded down, certain parts being broken away for convenience of illustration, and Fig. 4 is a section on line %4 of Fig I.

In the construction shown in the draw ings, the envelop is of manila paper, or other suitable material, and is folded up into flat, tubular form with side laps 1 and 2, and a bottom flap 3, overlapping and pasted together to form the back wall of the envelop. These flaps are preferably integral with the front wall of the en velop, as are also the folding flaps used to close the filling end of the envelop.

The envelop may be made up from a blank completely out or shaped before folding, or can first be folded up to rectangular shape and then cut away at the corners to form the folding tongues 4c and 5, the former being integralwith the front wall and the latter integral with the rear Wall of the envelop. These flaps are of triangular outline with the triangle truncated at its apex, and are of the same size and shape, so that they can fold down along their base line 6 against the rear wall of the envelop. A metal fastener 7 is passed through the overlapping side flaps 1 and 2 which make up the rear wall, and is in position for engagement with alined openings in the folding flaps, each of which openings may be provided on its outer surface with a reinforcing eyelet 8.

it is an advantage of'this construction that when the envelop is to be filled the folding flaps can be spread apart at the open mouth of the envelop and so in a sense will act as guides to direct into the envelop the circulars, magazines, or other merchan-' disc to be inserted therein, and when thus acting as guides they protect the front and rear walls against tearing and contribute to rapid filling. After the merchandise is inside, the two flaps 4 and 5 are folded down along their common base line 6 for attachment to the metal fastener 7, and by this arrangement the closure end of the envelop is stiffened and strengthened and there is less danger of losing the merchandise than is the case when the usual single flap is used.

If desired, the flap 5 on the back of the envelop can be folded over into the envelop to serve binder for the catalogue or other papers inclosed, allowing the front flap 4 to fold back as before into engagement with the metal fastener 7. When used in this way the flap 5 protects the flap 4 from the crowding of the inclosure and strengthens and reinforces the closure end of the envelop.

I claim:

1. A open-ended merchandise enlop, l'iaving at its open end a pair of trope idal flaps of the same size and shape, one

carried by the front all of the envelop and the other by the rear wall thereof and integral therewith, said flaps being folded down over against said rear wall, and each being provided at its (enter with an eyelet, and a metal fastener in the rear wall of said envelop, with tangs .issed outward through said eyelets, thereby holding said envelop closed.

2. A flat merchandise envelop. having side flaps and a bottom flap pasted together to form a rear wall, a front wall integral with said rear wall, and a pair of flaps, one carried by the front wall and the other by the rear wall, said flaps being folded over ,against the rar wall and there fastened in place; said rear wall having a longitudinally pasted seam down its center. sald flaps being of the same size and each of trapezoidal form, and both folded over backward along the same line and lying flat, leaving the body of the envelop rectangular in shape with a double flap at its closure end and a metal fastener passed through the double thickness of material at said longitudinally pasted seam, an eyeletat the center of each end flap, said metal fastener having its tangs passed through said eyelets and holding said flaps in place, substantially as de-' scribed.

In testimony whereof I attix my signature, in presence of two witnesses.
